Most cancers become deadly by maintaining a low profile, only showing symptoms when they’re too advanced to treat. Ovarian and gastroesophageal cancers are among the most notorious for this sly disease progression, often leading to late-stage diagnoses., have developed a highly sensitive blood test capable of detecting a key protein produced by cancer cells that shows promise for early detection.
“Transposons are normally expressed in sperm and egg and during embryogenesis, so there are some circumstances where you have nonpathobiological expression of transposons,” says Rockefeller research associate professor John LaCava, a co-author on the paper, who specializes in LINE-1 research. “But otherwise, these ‘jumping genes’ are silenced within the genome, because their activity creates stress and insults in the cell.
Because carcinoma cells make ORF1p from the onset of disease, researchers have long sought a sensitive, accurate test to detect ORF1p as early as possible. The ability to spot it in patients before a cancer has a chance to spread could potentially save lives.
The researchers also analyzed the plasma of 400 healthy people aged 20–90 who’d donated blood to the Mass General Brigham Biobank; ORF1p was undetectable in 97–99% of them. Of the five people who did have detectable ORF1p, the person with the highest level was found six months later to have advanced prostate cancer.Another potential use of the assay is monitoring how a patient is responding to cancer therapy.
